ALSA: hda - Fix initialization of hp pins with master_mute in Realtek
 
Some Reatlek model quirks use master_mute bool switch for controlling
the master-mute of outputs.  For these cases, the initialization of HP
pins/amps were forgotten during the transition to the common automute
helper function in 3.0 development time, and resulted in the muted HP
output as default.

This patch fixes the issue by adjusting the HP output explicitly with
master_mute switch.
